Description
- The present technology relates to a technical field of a sound output device that is fitted to an ear and used to output sound.
- There are sound output devices that are fitted to ears to be used as headphones or earphones and output sound from speakers. In recent years, such sound output devices are increasing used in outdoor situations in addition to indoor situations. A sound output device includes a speaker that outputs sound to the inside and a control circuit board that controls driving of the speaker or the like disposed therein.
- Some of such sound output devices have a device main body in which a speaker or the like is disposed and a fitting assisting body that assists fitting of the device main body to an auricle (see
Patent Document 1 to Patent Document 4). - The sound output devices described in
Patent Document 1 toPatent Document 4 are provided with a device main body in which a speaker is disposed therein and a fitting assisting body coupled to the device main body or formed integrally with the device main body. The fitting assisting body is referred to as an earmuff portion, a supporter, an anchor, an arm portion, or the like, and protrudes in a crooked state from the device main body. - In the sound output devices described in
Patent Document 1 toPatent Document 4, the fitting assisting body is inserted into an ear concha, an outer peripheral surface of the fitting assisting body is placed on an anterior edge of an antihelix, and the fitting assisting body assists fitting of the device main body to an ear. -

- Incidentally, since human ears have individual differences in shape and size, there is a possibility that a user fitted with a sound output device may feel a sense of discomfort depending on the shape and size of a fitting assisting body. For example, in a case where the shape and size of the fitting assisting body of the sound output device to be fitted do not match the shape and size of the ear of the user, there is a possibility that the sound output device is in an unstable state where the sound output device easily falls off from the ear, or the fitting assisting body is inserted into a cavum conchae in a cramped state, and there is a possibility that a comfortable fitting feeling cannot be obtained and usability is reduced.
- Furthermore, since the fitting assisting body protrudes from the device main body like an arm, there is a case where a sense of discomfort is generated when the sound output device is gripped, and there is also a problem in that the fitting assisting body is easily damaged when, for example, the fitting assisting body is accidentally dropped or brought into contact with another article, and again, there is a possibility that the usability is impaired.
- On the other hand, in a sound output device as described above, it is desirable that a stable fitting state in a state of being fitted to an ear be obtained.
- It is therefore an object of the sound output device of the present technology to improve usability and secure a state of stable fitting to an ear.

- With this arrangement, fitting to the ear is achieved with the first bulging portion that bulges toward the outer peripheral side with respect to the second portion partially inserted into the space ranging from the ear concha to the intertragic notch in each of inside the tragus and inside the antitragus, and the second bulging portion that bulges toward the outer peripheral side with respect to the second portion inserted into the ear concha inside the antihelix.
- Second, in the sound output device described above, it is desirable that the first bulging portion be partially pressed by each of the tragus and the antitragus, and the second bulging portion be pressed by the antihelix.
- With this arrangement, the first bulging portion is pressed by the tragus and the antitragus in a state of being inserted into the intertragic notch and the ear concha, and the second bulging portion is pressed by the antihelix in a state of being inserted into the ear concha.
- Third, in the sound output device described above, it is desirable that the first portion have an outer surface formed in a shape of a curved surface projecting outward.
- With this arrangement, the outer surface formed in a shape of a curved surface projecting outward is pressed against each part of the ear.
- Fourth, in the sound output device described above, it is desirable that the first portion be constituted by a first insertion portion positioned on the antitragus side and a second insertion portion positioned on the tragus side in a state where the sound output device is fitted to the ear, and the first portion be formed in an asymmetric shape in a direction in which the first insertion portion and the second insertion portion are continuous, and a maximum width of the first insertion portion be larger than a maximum width of the second insertion portion.
- With this arrangement, the first portion is formed in a shape corresponding to the intertragic notch and the ear concha.
- Fifth, in the sound output device described above, it is desirable that the housing be provided with a sound guiding tube having a sound guiding space that is continuous with the first portion, and the speaker be disposed inside the first portion.
- With this arrangement, the speaker is disposed inside the first portion that is continuous with the sound guiding tube.
- Sixth, in the sound output device described above, it is desirable that a battery be disposed inside the second portion, and the speaker and the battery be disposed in directions in such a way as to be the same in thickness direction.
- With this arrangement, the housing is reduced in size in the direction in which the first portion and the second portion are continuous.
- Seventh, in the sound output device described above, it is desirable that a magnet to be attracted to an attraction body disposed in a storage case in a state of being stored in the storage case be disposed inside the first portion, the speaker and the battery be disposed at positions shifted in a direction orthogonal to the thickness direction, and the magnet be disposed at a position facing the battery in the thickness direction.
- With this arrangement, the magnet is disposed in a space between the speaker and the battery.
- Eighth, in the sound output device described above, it is desirable that a portion on a side opposite to the first portion across the second portion be provided as a third portion, and an antenna for wireless communication be disposed inside the third portion.
- With this arrangement, the antenna is disposed at a position spaced apart from the first portion to be inserted into the ear concha.
- Ninth, in the sound output device described above, it is desirable that a control circuit board that controls at least the speaker and an antenna board on which the antenna is mounted be disposed inside the housing, and the control circuit board and the antenna board be disposed in directions in such a way as to be the same in thickness direction.
- With this arrangement, the housing is reduced in size in the thickness direction of the control circuit board.
- Tenth, in the sound output device described above, it is desirable that the control circuit board, the antenna board, and the speaker be disposed in directions in such a way as to be the same in thickness direction.
- With this arrangement, the housing is further reduced in size in the thickness direction of the control circuit board.

housing 2 has a configuration in which theedge 6 a of thecase portion 6 in thefirst case 3 and theedge 11 a of the outerdiameter changing portion 11 in thesecond case 4 are coupled by bonding or the like, and theedge 10 a of theconstricted portion 10 in thesecond case 4 and theedge 12 a of theperipheral surface portion 12 in thethird case 5 are coupled by bonding or the like (seeFIGS. 3 and 4 ). - A
speaker 14 and amagnet 15 are disposed inside thecase portion 6 in the first case 3 (seeFIGS. 5 to 7 ). Thespeaker 14 is formed in a flat rotationally symmetric shape with its thickness direction (axial direction) in the left-right direction. Thespeaker 14 is disposed at a position where thespeaker 14 caps thesound guiding space 7 a of thesound guiding tube 7. Themagnet 15 is disposed at a position spaced apart from thesound guiding space 7 a. Note that thespeaker 14 may be downsized and disposed in thesound guiding space 7 a. - In a state where the
sound output device 1 is stored in a storage case described later for storing thesound output device 1, themagnet 15 is attracted to an attraction body disposed in the storage case. Thus, a stable storage state of thesound output device 1 with respect to the storage case is secured by themagnet 15 being attracted to the attraction body. - A
battery 16 is disposed inside thesecond case 4. Thebattery 16 is formed in a substantially cylindrical shape with its thickness direction (axial direction) in the left-right direction. Thebattery 16 is disposed in a direction in which the thickness direction is the same as that of thespeaker 14. Thebattery 16 is disposed at a position shifted from thespeaker 14 in a direction orthogonal to the thickness direction, and is disposed at a position facing themagnet 15 in the left-right direction. - As described above, since the
speaker 14 and thebattery 16 are disposed at positions shifted in the direction orthogonal to the thickness direction and themagnet 15 is disposed at a position facing thebattery 16 in the thickness direction, themagnet 15 is disposed in a space between thespeaker 14 and thebattery 16, and thesound output device 1 can be downsized by effective use in a space inside thehousing 2. - A
board unit 17 is disposed inside thethird case 5. Theboard unit 17 has acontrol circuit board 18, anantenna board 19, and a holdingbracket 20. - The
control circuit board 18 is formed in a substantially disk shape with its thickness direction in the left-right direction that is slightly smaller than thecircumferential portion 12 of thethird case 5. Thecontrol circuit board 18 is a board that controls each unit disposed inside thehousing 2, for example, thespeaker 14 or thebattery 16, and is disposed so as to face thebattery 16. - The
antenna board 19 is formed in a substantially disk shape with its thickness direction in the left-right direction that is slightly smaller than thecircumferential portion 12 of thethird case 5. Theantenna board 19 is disposed so as to face thecontrol circuit board 18 in the left-right direction, and is positioned closer to thecover surface portion 13 than thecontrol circuit board 18. Anantenna 21 is mounted on a surface of theantenna board 19 on thecover surface portion 13 side. Theantenna 21 is mounted on an outer peripheral portion of theantenna board 19, for example, and has a function of performing wireless communication by transmitting and receiving sound signals. - The holding
bracket 20 has anattachment plate portion 20 a formed in a plate shape that faces the left-right direction, andengagement protrusions attachment plate portion 20 a from an outer peripheral portion of theattachment plate portion 20 a. The engagement protrusions 20 b, 20 b, and 20 b are positioned spaced apart in the circumferential direction. Theantenna board 19 is attached to theattachment plate portion 20 a of the holdingbracket 20. The engagement protrusions 20 b, 20 b, and 20 b of the holdingbracket 20 are positioned on the outer peripheral side of thecontrol circuit board 18, and have distal ends engaged with thesecond case 4 or thethird case 5. - The engagement protrusions 20 b, 20 b, and 20 b of the holding
bracket 20 are engaged with thesecond case 4 or thethird case 5 so that the holdingbracket 20 is set at a predetermined position inside thethird case 5, and theantenna 21 mounted on theantenna board 19 attached to the holdingbracket 20 is positioned with respect to thethird case 5. Thus, theantenna 21 is positioned at a position adjacent to thecover surface portion 13. - Each one of a plurality of connection cables (not illustrated) has one end connected to the
control circuit board 18, and the other end connected to thespeaker 14, thebattery 16, or theantenna board 19. A part of the connection cable connected to thespeaker 14 is inserted through the cable insertion hole of thepartition plate portion 9. - As described above, in the
sound output device 1, thecontrol circuit board 18 and theantenna board 19 are disposed inside thehousing 2, and thecontrol circuit board 18 and theantenna board 19 are disposed in directions in such a way as to be the same in thickness direction. - Thus, the
housing 2 is reduced in size in the thickness direction (left-right direction) of thecontrol circuit board 18, and thesound output device 1 can be downsized. - Furthermore, the
control circuit board 18, theantenna board 19, thespeaker 14, and thebattery 16 are also disposed in directions in which thickness directions are in the same direction. - Thus, the
housing 2 is further reduced in size in the thickness direction of thecontrol circuit board 18, and thesound output device 1 can be further downsized. - Each circuit formed on the
control circuit board 18 is connected with apower button 22 and a microphone (not illustrated), and thepower button 22 and the microphone are positioned on the outer peripheral side of thecontrol circuit board 18 so as to be spaced apart from each other in the circumferential direction. Thepower button 22 is disposed so as to be inserted into thebutton disposition hole 12 b of thethird case 5, and the microphone is disposed at a position corresponding to themicrophone hole 12 c of thethird case 5. -
Connection terminals control circuit board 18 opposite to theantenna board 19. Theconnection terminals control circuit board 18 so as to be arranged side by side in the circumferential direction, and protrude from thecontrol circuit board 18 in the thickness direction of thecontrol circuit board 18. Distal end portions of theconnection terminals second case 4. - Note that, in the
sound output device 1, entry of moisture into thehousing 2 through thebutton disposition hole 12 b, themicrophone hole 12 c, the terminal disposition holes 10 b, 10 b, and 10 b, and thesound guiding tube 7 is prevented by, for example, a waterproof sheet (not illustrated). - An
ear pad 24 formed with the use of, for example, a rubber material is attached to thesound guiding tube 7 of thesecond case 4. Theear pad 24 can be attached to and detached from thesound guiding tube 7. In a state of being attached to thesound guiding tube 7, theear pad 24 is partially engaged with the couplingannular portion 7 b of thesound guiding tube 7 so as to be stably attached to thesound guiding tube 7 without easily falling off from thesound guiding tube 7. - Note that the
sound output device 1 may have a configuration without theear pad 24. - In the
sound output device 1 configured as described above, thecase portion 6 of thefirst case 3 and the outerdiameter changing portion 11 of thesecond case 4 constitute afirst portion 30, theconstricted portion 10 of thesecond case 4 constitutes asecond portion 40, and a portion on a side opposite to thefirst portion 30 across thesecond portion 40 constitutes a third portion 50 (seeFIGS. 3, 7, and 8 ). - The
first portion 30 has anouter surface 30 a formed in a shape of a curved surface projecting outward. Thefirst portion 30 is a portion to be inserted into a space ranging from theear concha 109 to theintertragic notch 116 in a state where thesound output device 1 is fitted to theear 100. - Both the
first portion 30 and thesecond portion 40 are formed in a substantially elliptical shape or a shape close to an elliptical shape when viewed from the left-right direction, and thefirst portion 30 has an outer shape larger than that of the second portion 40 (seeFIG. 8 ). Thefirst portion 30 is provided with a protrudingportion 31 that protrudes outward in a direction orthogonal to the left-right direction with respect to thesecond portion 40. In the elliptical shapes, when major axis directions are expressed by P1 and P2 and minor axis directions are expressed by Q1 and Q2, the protrudingportion 31 protrudes outward with respect to thesecond portion 40 in the entire circumferential direction other than directions excluding the major axis direction P1. The protrudingportion 31 is constituted by a first bulgingportion 32 that bulges toward the major axis direction P2 side, a second bulgingportion 33 that bulges toward the minor axis direction Q1 side, and a third bulgingportion 34 that bulges toward the minor axis direction Q2 side. - The
first portion 30 is formed in a shape asymmetric with respect to the major axis directions P1 and P2 as viewed from the left-right direction, and is constituted by afirst insertion portion 35 positioned on the minor axis direction Q1 side and asecond insertion portion 36 positioned on the minor axis direction Q2 side. A degree of bulging of thefirst insertion portion 35 with respect to thesecond portion 31 is larger than that of thesecond insertion portion 36, and a maximum width H1 of thefirst insertion portion 35 is larger than a maximum width H2 of thesecond insertion portion 36 in a direction in which thefirst insertion portion 35 and thesecond insertion portion 36 are continuous. - As described above, the
first portion 30 is constituted by thecase portion 6 of thefirst case 3 and the outerdiameter changing portion 11 of thesecond case 4, and also includes theedge 6 a of thecase portion 6 and theedge 11 a of the outerdiameter changing portion 11. A portion where theedge 6 a of thecase portion 6 and theedge 11 a of the outerdiameter changing portion 11 are coupled is formed as aboundary line 60 between thefirst case 3 and thesecond case 4, and theboundary line 60 is formed in a three-dimensional curve (seeFIGS. 3, 7, and 9 ). - In the
sound output device 1, thespeaker 14 is disposed inside thefirst portion 30, thebattery 16 is disposed inside thesecond portion 40, and thespeaker 14 and thebattery 16 are disposed at positions spaced apart in the left-right direction and also spaced apart in a direction orthogonal to the left-right direction (seeFIGS. 7 and 9 ). At this time, anend surface 14 a of thespeaker 14 on the side opposite to thesound guiding tube 7 in the left-right direction and anend surface 16 a of thebattery 16 on the side facing themagnet 15 are located at substantially the same position or positions adjacent to each other. - Assuming that a surface including the
end surface 14 a of thespeaker 14 and theend surface 16 a of thebattery 16 is a sharedplane 61, theboundary line 60 is included in the sharedplane 61 or located at a position adjacent to the sharedplane 61 from a position along the outer periphery of thespeaker 14 to a position along the outer periphery of thebattery 16, and is a three-dimensional curve connecting the maximum outer shape of thefirst portion 30. - <Storage Case>
- Next, a
storage case 70 in which thesound output device 1 is stored will be described (seeFIGS. 10 and 11 ). - The
storage case 70 has acase body 71 into which thesound output devices cover body 72 for opening and closing thecase body 71, and thecover body 72 is rotatably supported by thecase body 71. Thestorage case 70 has a power supply terminal (not illustrated) for receiving electric power, and also functions as a charger for charging thebatteries sound output devices - Storage recesses 73 and 73 are formed in the
case body 71, one of the storage recesses 73 for storing thesound output device 1 for theleft ear 100, and theother storage recess 73 for storing thesound output device 1 for theright ear 100. In thecase body 71, anextraction recess 71 a is formed between the storage recesses 73 and 73. Note that thesound output device 1 for theleft ear 100 and thesound output device 1 for theright ear 100 are formed in a symmetrical shape. -
Terminal portions case body 71, and theterminal portions storage recess 73. - An
attraction body 75 is disposed inside the case body 71 (seeFIG. 11 ). Theattraction body 75 is a magnetic body such as a magnet or metal, and is disposed at a position closer to the back side than the opening of thestorage recess 73 and near thestorage recess 73. - Note that, although an example in which the
magnet 15 is provided in thesound output device 1 has been described above, in a case where a magnet is provided as theattraction body 75 in thestorage case 70, a magnetic body may be provided in thesound output device 1 instead of themagnet 15. - In a state where the
cover body 72 is opened, thesound output device 1 excluding a part thereof is inserted into thestorage recess 73, and thus thesound output device 1 is stored and held in thestorage case 70. When thesound output device 1 is inserted into thestorage recess 73, themagnet 15 is attracted by theattraction body 75, and thus thesound output device 1 is held in thecase body 71. - In a state where the
sound output device 1 is held in thecase body 71, thethird case 5 is brought into a state of protruding from thestorage recess 73, and agap 80 is formed between theextraction recess 71 a and thethird case 5. Furthermore, in a state where thesound output device 1 is held in thecase body 71, theterminal portions second case 4, and theterminal portions corresponding connection terminals battery 16 can be charged. - The
sound output device 1 is protected by thecase body 71 being blocked by thecover body 72. - The
sound output device 1 can be taken out from thecase body 71 by inserting a finger into thegap 80 formed between theextraction recess 71 a and thethird case 5 and picking up thesound output device 1. - At this time, there is a certain distance L between the
gap 80 into which a finger is to be inserted and themagnet 15 attracted to theattraction body 75. As described above, since thegap 80 and themagnet 15 are not positioned in proximity to each other, the distance L is set to a sufficient length, and the portion where thesound output device 1 is attracted to theattraction body 75 and the portion into which the finger is inserted are sufficiently separated from each other, it is possible to cancel the state of themagnet 15 being attracted to theattraction body 75 with a small force by using the attracted portion as a fulcrum and the portion into which the finger is inserted as a point of effort. - Thus, due to the distance L, the
sound output device 1 can be easily and reliably taken out from thecase body 71. - <Fitting Sound Output Device to Ear>
- Next, a state where the
sound output device 1 is fitted to theear 100 will be described (seeFIGS. 12 and 13 ). Note that, in the following, a state of being fitted to theleft ear 100 will be described as an example. - In a state where the
sound output device 1 is fitted to theear 100, thesound guiding tube 7 and theear pad 24 are inserted into the space ranging from theear concha 109 to theintertragic notch 116, and a part of theear pad 24 is inserted into theear canal 113. At this time, thefirst portion 30 is also inserted into the space ranging from theear concha 109 to theintertragic notch 116. - The first bulging
portion 32 is partially inserted into each of the inside of thetragus 111 and the inside of theantitragus 110, and the second bulgingportion 33 and the third bulgingportion 34 are inserted into theear concha 109. The first bulgingportion 32 is pressed by thetragus 111 and theantitragus 110, the second bulgingportion 33 is pressed by theantihelix 105, and thefirst portion 30 is pressed by each of the three portions of theear 100. - In a state where the
sound output device 1 is fitted to theear 100 as described above, the first bulgingportion 32 is partially pressed by each of thetragus 111 and theantitragus 110, and the second bulgingportion 33 is pressed by theantihelix 105. - Thus, in a state of being inserted into the
intertragic notch 116 and theear concha 109, the first bulgingportion 32 is pressed by thetragus 111 and theantitragus 110. At the same time, in a state of being inserted into theear concha 109, the second bulgingportion 33 is pressed by theantihelix 105. Thus, it is possible to secure a state where thesound output device 1 is stably fitted to theear 100. - Furthermore, in the
sound output device 1, since theouter surface 30 a of thefirst portion 30 to be inserted into theintertragic notch 116 and theear concha 109 is formed in a shape of a curved surface projecting outward, theouter surface 30 a formed in a shape of a curved surface projecting outward is pressed against each part of theear 100. Thus, it is possible to secure a state where thesound output device 1 is comfortably fitted to theear 100 without causing a sense of discomfort. - Moreover, the
first portion 30 is constituted by thefirst insertion portion 35 positioned on theantitragus 110 side and thesecond insertion portion 36 positioned on thetragus 111 side in a state of being fitted to theear 100. Thefirst portion 30 is formed in an asymmetric shape in the direction in which thefirst insertion portion 35 and thesecond insertion portion 36 are continuous, and the maximum width H1 of thefirst insertion portion 35 is larger than the maximum width H2 of thesecond insertion portion 36. - Thus, since the
first portion 30 is formed in a shape corresponding to theintertragic notch 116 and theear concha 109, it is possible to secure a state where thesound output device 1 is stably and more comfortably fitted to theear 100. - <Summary>
- As described above, in the
sound output device 1, thefirst portion 30 is provided with the first bulgingportion 32 and the second bulgingportion 33, each of which bulges toward the outer peripheral side with respect to thesecond portion 40, and thesound output device 1 is fitted to theear 100 with the first bulgingportion 32 partially inserted into the space ranging from theear concha 109 to theintertragic notch 116 in each of inside thetragus 111 and inside theantitragus 110, and the second bulgingportion 33 inserted into theear concha 109 inside theantihelix 105. - Thus, the
sound output device 1 is fitted to theear 100 with the first bulgingportion 32 that bulges toward the outer peripheral side with respect to thesecond portion 40 partially inserted into theintertragic notch 116 in each of inside thetragus 111 and inside theantitragus 110, and the second bulgingportion 33 that bulges toward the outer peripheral side with respect to thesecond portion 40 inserted into theear concha 109 inside theantihelix 105. - With this arrangement, the
sound output device 1 is fitted to theear 100 without a fitting assisting body that protrudes like an arm, and this makes it possible to obtain a comfortable fitting feeling, improve usability, and secure a state of stable fitting to theear 100. - Furthermore, the
housing 2 is provided with thesound guiding tube 7 having thesound guiding space 7 a that is continuous with thefirst portion 30, and thespeaker 14 is disposed inside thefirst portion 30. - Thus, since the
speaker 14 is disposed inside thefirst portion 30 that is continuous with thesound guiding tube 7, it is possible to secure a sufficient space for disposing thespeaker 14 inside thehousing 2 and also secure a good state of sound output. - Moreover, the
battery 16 is disposed inside thesecond portion 40, and thespeaker 14 and thebattery 16 are disposed in directions in such a way as to be the same in thickness direction. - Thus, the
housing 2 is reduced in size in the direction in which thefirst portion 30 and thesecond portion 40 are continuous, and thesound output device 1 can be downsized. - Furthermore, a portion on a side opposite to the
first portion 30 across thesecond portion 40 is provided as thethird portion 50, and theantenna 21 for wireless communication is disposed inside thethird portion 50. - Thus, since the
antenna 21 is disposed at a position spaced apart from thefirst portion 30 to be inserted into theear concha 109, it is possible to secure a good state of input and output of signals to and from theantenna 21. - <Present Technology>
